2010-04-13Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser
This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-02-23AVR32: Move addrspace.h to arch-directory, and move some functions from io.h ↵Olav Morken
to addrspace.h The AVR32A architecture (which AT32UC3A-series is based on) has a different memory layout than the AVR32B-architecture. This patch moves addrspace.h to an arch-dependent directory in preparation for AT32UC3A-support. It also moves some address-space manipulation functions from io.h to addrspace.h.

2008-12-17avr32: Remove second definition of virt_to_phys()Haavard Skinnemoen
The second definition introduced by 65e43a1063 conflicts with the existing one. Also, convert the existing definition to use phys_addr_t. The volatile qualifier is still needed due to brain damage elsewhere. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
2008-12-15Introduce virt_to_phys()Kumar Gala
virt_to_phys() returns the physical address given a virtual. In most cases this will be just the input value as the vast majority of systems run in a 1:1 mode. However in systems that are not running this way it should report the physical address or ~0 if no mapping exists for the given virtual address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-04-13Introduce phys_size_t and move phys_addr_t into asm/types.hKumar Gala
Also add CONFIG_PHYS_64BIT on powerpc to deal with 32-bit ppc's that have larger physical addresses like 44x, 85xx, and 86xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-12-13Introduce map_physmem() and unmap_physmem()Haavard Skinnemoen
map_physmem() returns a virtual address which can be used to access a given physical address without involving the cache. unmap_physmem() should be called when the virtual address returned by map_physmem() is no longer needed. This patch adds a stub implementation which simply returns the physical address cast to a uchar * for all architectures except AVR32, which converts the physical address to an uncached virtual mapping. unmap_physmem() is a no-op on all architectures, but if any architecture needs to do such mappings through the TLB, this is the hook where those TLB entries can be invalidated.

2007-02-21[PATCH v3] Add sync to ensure flash_write_cmd is fully finishedHaiying Wang
Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command is fully finished. The sync() is defined in each CPU's io.h file. For those CPUs which do not need sync for now, a dummy sync() is defined in their io.h as well. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com>
